Abstract: ABSTRACT OF THE DISCLOSURE      In  this  cylindrical,  magnetically-enhanced,  sputtering  catho-de, the magnetic field at the cathode target is generated by apply-ing an electric current through a hollow electrical conductor dis-posed within a tubular target, so that the electric current flowing along  this conductor  induces circular magnetic lines concentrical-ly around its axis. By biasing negatively the tubular target immers-ed in a low pressure gas, a glow discharge is generated. Electrons, emitted from the target surface are accelerated radially by the elec-tric field, but deviated perpendicularly by the magnetic field. The resulting motion is confined in a spirally-shaped area centered on the conductor axis.

Abstract: Method and Apparatus for Correcting Abnormal Cardiac Activity by Low Energy Shocks Abstract The present invention relates to a method and apparatus for delivering two or more individual low-level pulses to correct certain cardiac arrhythmias such as high-rate ventricular tachycardia and ventri-cular fibrillation; at least the latter shocks are delivered in synchronism with a repeatable character-istic of the heart's electrical activity.  Basically, the apparatus comprises an electrode sensor placed in the right ventricle of the heart or in the coronary sinus to act as a detector for the electrical activity of the heart.  Connected to the electrode sensor is an arrhythmia detector chosen to detect such arrhythmias as ventricular tachycardia and ventricular fibrillation. Upon detection of one of these arrhythmias, the detector issues a signal which is interpreted by a programmable logic device to activate an energy storage device for delivering a first low-level shock to the heart through a shock delivering electrode.  A slew rate detector is then activated by the logic device.  The output of the slew rate detector is fed to a comparator to be compared with a continually updated reference signal supplied by the logic device.  When the slew rate out-put equals or exceeds the value of the reference signal, the comparator issues a signal which activates the energy storage device to issue a second low-level shock to the heart through the shock delivering electrode. Additional shocks may be delivered in a manner similar to the delivery of the second shock under the control of the logic device.

Abstract: INVENTOR:   FRITZ MEYER            INVENTION:  CIRCUIT ARRANGEMENT CONTAINING WIRE MATRIX FOR             SIGNAL TRANSMISSION IN ELEVATOR INSTALLATIONS     ABSTRACT OF THE DISCLOSURE             The bidirectional transmission apparatus contains as an essential element a wire matrix utilised in a two-fold or dual manner.  The wire matrix comprises two groups of column conductors, each group being provided for one of the two signal transmission directions, and one group of line conductors common to all column conductors.  A control unit forms a component of a microprocessor and cyclically controls the line conductors and the column conductors are synchronously scanned and activated, whereby signal transmitters and signal receivers connected to the intersection or crossing points of the wire matrix are detected and controlled in a pulsed manner.  The frequency and scanning ratio of the cyclical scanning operation are selected such that even the shortest contact periods to be expected are reliably detected and that, when opto-electronic indicator or display elements are activated, a continuous light or radiation of sufficient intensity is visually discernible.          Due to the functional two-fold utilization of  the  line conductors as well as due to the cyclical operation a high transmission capacity is ensured even if the electronic and installational expense is highly reduced.  Using, for example, an 8 by 16-wire matrix there thus can be detected and activated a maximum of sixty-four call and limit or terminal switch signals  as  well  as  sixty-four  signallings  which  are simultaneously present at the wire matrix.

Abstract: ABSTRACT  METHOD OF MAKING OXIDE FILMS       Oxide (HmOn) films are grown by evaporation from separate sources of element (R) and an oxide (MrOs) which serves as the oxygen source.  The oxide (MrOs) should sublimate congruently; i.e., without decomposing into oxygen and its constituent element (M).  On the growth surface this oxide (MrOs) can react with the element (R) to form another oxide (RmOn) that is thermodynamically more stable:                 mR + MrOs -> RmOn + MrOs-n Using this technique, films of Al2O3, MgO, SlO2, and MgAl2O4 have been grown using As2O3 or Sb2O3 as the oxygen source.

Abstract: ELECTROPHORESIS      USING ALTERNATING TRANSVERSE ELECTRIC FIELDS            Abstract of the Disclosure Disclosed are an apparatus for and a method of electro-phoretically separating particles by electric fields which are transverse to each other, which alternate be-tween respective high and low intensities out of phase with each other at a frequency related to the mass of the particles and which move the particles in an overall direction transverse to the respective directions of the fields.  For separating large macromolecules, at least one of the fields preferably has  an intensity gradient in a direction transverse to its own.  The new arrangement makes it possible to: (1) separate particles (molecules) larger in size than those able to be separated with previ-ously known techniques, (2) carry out separation at higher speed and at better resolution than is possible with previously known techniques, and (3)  concurrently sepa-rate particles which differ greatly in mass (molecular weight).

Abstract: ABSTRACT:           In video equipment for recording a colour video signal on a magnetic tape a transmission method is now proposed which will be denoted "colour shift" method. Therein the composite colour video signal which is formed by a sequence of analogue line signals is sampled, as a result of which each analogue line signal is converted into a time-discrete line signal formed by a plurality of line signal samples occurring at a rate fs,each  sample being formed by the sum of a luminance and a chrominance signal sample. These time-discrete line signal are sub-mitted to a scrambling operation in which, in accordance with a predetermined pattern, a number of line signal sam-ples is selected from the line signal samples of a group of time-discrete line signals for assembling time-discrete auxiliary line signals. This selection is effected such that of all those line signal samples which together represent a given time-discrete auxiliary line signal the associated chrominance signal samples all have the same polarities. As a result, the chrominance signal is con-verted without bandwidth limitation to lower frequency band, while it continues to be located within the frequency band occupied by the luminance signal. This new composite color video signal can now, after having been converted into an analogue signal, be transposed in its totality to a suitable transmission band by means of frequency modula-tion.

Abstract: ABSTRACT OF THE DISCLOSURE         Automatic wave solder apparatus having a fluxer section, preheater section and wave soldering section through which circuit boards are passed by a conveyor.  All of the major process para-meters are monitored by a microprocessor.  One specific parameter controlled is the temperature of the boards exiting from the preheater system.  Preheating is carried out by two axially spaced banks of heaters, the upstream one supplying the major quantity of heat and the downstream one supplying sufficient heat to boost the temperature to the desired value.  A pyrometer located in the zone between the two banks of heaters measures the heat radiated from the boards and this information is converted by the microprocessor to an appropriate instruction to the second bank of heaters.  The soldering section has a solder pot assembly particularly adapted to the automatic nature of the apparatus.        The pot can be jacked to the correct height according to the length of leads projecting from the boards under control of the microprocessor.  Irrespective of the solder pot height the struc-ture of the solder nozzle ensures constant values for the rear flowing portion of the wave.  The pot may be swung out for cleaning.
